This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems, to activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.

My Hisense 32" inch tv has started making a popping sound and is static and it turns off then turns on and load then "pop" it off and it does it again then turns on stays on for about 10 mins with no sound...

Sounds like you have a bad power supply board. Either replace the TV or get it fixed (probably not worth spending too much on considering how cheap new 32" TVs are now).

Audio Static on Sharp 32SC26B

Chances are your main board is bad, its where all the sounds are producted, a new board should correct the issue, its something you can install yourself with a screw driver, have the set unplugged for about a day before replacing the board so all the capacitors are discharged..you can get a new board at shopjimmy.

When I turn the tv on, it sounds like static electricity coming from the back.

Check its final anode connection for arcing. You have to replace the final anode rubber boot, if arcing is here. Seek tech support. This is a dangerous work, for an un-experienced one.

I put banana clips on the wires and plugged them into the Insignia 200w audio receiver and everything sounds static tv and music

For temporary just for testing it ok.. but using banana clips permanently it not a good idear because due to excesive sound vibration it will create static for sure to avoid that you may have to souldering those wired in place to avoid that static and causing eventual damage inside your receiver... any conection as to be well connected special went it time to connect a large amps., beside a turn table, you may look for a good ground.... I suggest to put a solid ground wire also betwen your tv set and your receiver
for eventual hi static discharge., also make sure use a power bar for more protection ...good luck

Static noise and blurry screen

You need to take your TV set to Service Center, because the inner parts, especially the flyback transformer, been damaged or worse, the connector broken, that's why you can hear the noise.

Screen turns green after 20 minutes of use

static line at top is a problem with the broadcast input. many cable boxes and satellites create this because they dont quite fill the true resolution that the tv is capable of. the green splotches sound like overheating of the lcd lamps. id return it for a new one.

TV video/audio problem

It may not need repair or replacement.
Unplug the set at least overnight; the CRT (picture tube) has voltages that may be as high as 30,000 volts and take time to bleed off. Believe me, it stings if it bites you.
Remove the rear housing of the set, then use a clean (preferably new) 2-3" paint brush to whisk away any dust deposits you see. This works best with the nozzle of your vacuum cleaner near the area you are cleaning.
The problem you describe can be caused by an accumulation of dust that is picking up moisture from the air and temporarily creating a path for high voltage to discharge which can cause all kinds of strange occurances such as you describe. The warmup of the set dries out this moisture removing the discharge path.    If you don't remove this dust buildup, it will eventually damage the high voltage circuit if not others as well. That high voltage is a healthy static charge and wasn't designed to supply a lot of current which it has to do when discharging.

TV randomely turns off

it may just be a static buildup from the dust.
open the tv and blow it out with a air compressor.
if that doest not work then the circuit may be overloading.
remember it stores a charge for days.
